EVERY 250 HOURS MAINTENANCE

Maintenance for every 50 hours service should be carried out
at the same time.

CHECK OIL LEVEL IN FINAL DRIVE CASE, ADD OIL

The parts and oil are at high temperature after the engine is stopped, and may cause serious burns.
●
Wait for the temperature to go down before starting the operation.
If there is still pressure remaining inside the case, the oil or plug may fly out.
●
Loosen the plug slowly to release the pressure.
Prepare a hexagonal wrench.
●
1. Set so that plug (F) is at the top, with plug (F) and plug
(P) prependicular to the ground.
2. Using a hexagonal wrench, remove plug (F) and check
that the oil level is within a range from the bottom of the
plug hole to a point 10 mm(0.4 in) below it.
3. If the oil level is too low, install plug (F), operate the travel
levers, and drive forward or in reverse to rotate the
sprocket one turn. Then repeat Step 2 to check again.
4. If the oil level is still too low, add engine oil through the
hole in plug (F) until the oil overflows.
5. After checking, install plug (F).
